 174           needing a ranlib program (STR #3209)

 188         - ppdOpen*() could crash if a keyword had no value string (something
 189           that cupstestppd looks for...)
 190         - cupsLangDefault() did not return the correct language on Mac OS X.
 191         - The Mac OS X USB backend did not handle aborted or stalled pipe

 203           (STR #3096, STR #3098, STR #3109, STR #3111, STR #3141)

 212           failed print jobs.
 213         - You can now modify a raw print queue (STR #3133)
 214         - Fixed a number of ppdi issues and added a unit test to validate that
 215           ppdc + ppdi can generate and import the same data (STR #3152)

 217           one printer or class added (STR #3094)
 218         - Since classes have never truly supported the printer-error-policy
 219           stuff added in CUPS 1.2, update the code to reflect the current
 220           reality and support only the retry-current-job policy for now
 221           (STR #3171)
 222         - Revised the password callback support (STR #2953)
 223         - ppdEmit*() did not choose between PageSize and PageRegion properly.
 224         - Make some fairly substantial changes to the Kerberos support code so
 225           that CUPS can work in multi-realm environments and does not require
 226           delegatable credentials.  Shared printing still requires delegation,
 227           however "delegation by policy" can be enabled in the KDC to make this
 228           all work.
 229         - "AccessLogLevel actions" did not hide client-error-not-found errors.
 230         - AP_FIRST_InputSlot did not work with number-up.

 234           while copying print data to a temporary file.

 236           causing reduced performance in some situations.
 237         - If a CGI process died before sending its MIME headers, the request
 238           would hang on the client.
 239         - The printer/class/job search feature on the web interface did not
 240           work (STR #3132)
 241         - The scheduler did not write the printers out for classes.
 242         - CUPS-Get-PPDs did not work properly when filtering by language,

 245           (configurable) to cancel or hold the job.

 247           filenames in the PPD file.

 255           incorrectly added the printer (STR #3095)
 256         - The scheduler no longer uses programs with insecure file
 257           permissions.
 258         - httpAssembleURI*() did not escape backslashes in hostnames.
 259         - The dnssd backend did not unquote "full names" before creating the
 260           device URI.
 261         - The scheduler now supports JobRetryInterval values less than 10
 262           seconds.
 263         - Updated the Spanish localization (STR #3090)
 264         - The scheduler did not redo Bonjour/DNS-SD registrations when updating

 268         - ppdOpen*() incorrectly loaded PPDs with multiple JobPatchFile
 269           keywords.
 270         - The network backends no longer report the SNMP "offline" or
 271           maintenance status bits since they are inconsistently implemented and
 272           often unreliable.
 273         - The scheduler no longer logs child processes killed via SIGKILL as
 274           "crashed".

 276         - Updated the HTML templates to use the final HTML 4 DOCTYPE (STR #3086)

 280         - The PPD compiler did not search for localization files properly
 281           (STR #3084)
 282         - cupsGetNamedDest() did not use the fallback default like
 283           cupsGetDests*() (STR #3082)
 284         - The scheduler now provides a LogTimeFormat directive to enable
 285           microseconds in the date and time that are logged.

 299         - SNMP lookups via side-channel did not work for NULL-VALUE and
 300           and OCTET-STRING OIDs containing nul characters.
 301         - The libusb-based USB backend did not work.
 302         - The scheduler did not set the printer-commands attribute correctly
 303           for some PPDs.
 304         - The ppdi utility did not work.
 305         - The web interface no longer uses multi-part output with old or broken

 314         - cupsResolveConflicts() did not resolve using the default option
 315           choice in some cases due to the mirror UIConstraints that are
 316           present in most PPD files.
 317         - The scheduler did not honor MIME type priorities.
 318         - The commandtops filter incorrectly used the JCLBegin code to end
 319           its jobs.
 320         - The default BrowseLocalProtocols value was not set properly.
 321         - Since the commandtops filter does not actually support ReportLevels
 322           all on its own, don't list that printer command by default for PS
 323           printers.
 324         - The scheduler did not give filters a chance to log errors or update
 325           printer attributes when a job was canceled.
